随着我国对外贸易的迅速发展,贸易摩擦已经由企业的微观层面向政府政策的宏观层面发展,反补贴已经成为国际贸易摩擦的新热点。补贴幅度确定是反补贴政策实施的关键和难点问题。文章基于系统思维,运用管理决策、计量经济等理论与方法,提出了补贴幅度确定的IEC间接弹性系数法,并选取中、美2006年铜版纸案件进行了实证研究并得出相应结论。 With the rapid development of China's foreign trade, trade friction has been developed from the micro-level of government to the macro-level of government policy. Countervailing subsidy has become a new hot spot in international trade friction. The determination of the scope of subsidies is the key and difficult issue of anti-subsidy policies. Based on systematic thinking, the use of management decision-making, econometrics and other theories and methods, this paper proposed IEC Indirect Elasticity Coefficient Method for determining the scope of subsidies, and selected 2006 cases of China and the United States to conduct empirical research and draw the corresponding conclusions.
